GENERAL KNOWLEDGE

Detailed explanation-1: -Radiant energy is the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment. Radiant energy sources include the entire electromagnetic radiation spectrum, including gamma rays, x-rays, radio frequencies, microwaves, light and heat.

Detailed explanation-2: -Radiant energy moves from one place to another in the form of electromagnetic waves or electromagnetic radiation. At its most elementary level, electromagnetic waves are made up of photons, which have no mass and move at the speed of light.

Detailed explanation-3: -Electromagnetic energy is radiant energy that travels in waves at the speed of light. It can also be described as radiant energy, electromagnetic radiation, electromagnetic waves, light, or the movement of radiation. Electromagnetic radiation can transfer of heat.

Detailed explanation-4: -radiant energy, energy that is transferred by electromagnetic radiation, such as light, X-rays, gamma rays, and thermal radiation, which may be described in terms of either discrete packets of energy, called photons, or continuous electromagnetic waves.
